This invention relates to mopwringers.

It is one of the objects of this invention to provide a mo wringer adapted to be mounted on a scru bing pail, scrubbing tank 'Lgf or the like in an improved. manner.

It is another object to provide a. mop wringer which may be operated by one hand of the operator in an improved manner leaving his other hand free to manipulate the 10 mop. f

It is another object to lprovide a vmop wringer which will be easy to operate and eiiicient in action. I i' Another is to provide a mop wringer in l5 which the moving parts effecting the wringing f or squeezing of the mop may be dis# posed in their'normal position so as not to interfere with placing the mop in the wringer or removing it therefrom.

It is another object of my invention-to provide an improved mop wringerof the type in which the mop is squeezed between two squeezing elements having relative bodily movement one toward the other,

25 It is another object to provide a mop Y wringer in which the maximum of squeezing pressure may be obtained with the minimum of effort on the part of the operator.

It is another object to provide a mop 30 wringer in which the parts after use automatically return to -a normal positionpermitting easy insertion of a mop in the wringer upon the next occasion of itsuse.

Another object is to provide a. mop wringer 35 of the class referred to which will be cheap and simple to manufacture and assemble and which admits ofrbeing formed-largely froml parts which may be stamped from'sheety metal. 4o

Referringtozthe drawings, have shown a mop wringer frame comprising slde frame elements` I-ll preferably formed from relativelylheavy sheet metal. A basket 3 formed from sheet metal andrcomprisi'ng a perforated bottomV 4v, a perforated frontlwall 5,and a perforated back wall 6is disposed between the frame elements 1 1. The basket 3 'is preferably not provided with side walls, but

isformed from a flat sheet byV bendingv the front and back walls at a rightlangle to the plane of the bottom. The lateral `o rside edges ofthe front, bottom' and back portions of thebasket thus formedabut upon the inner faces of the frame elements 1-1 A'plurality of tiebolts .f-f2 extend-through suitable perforations inthe frame'elements 1--1, and by means of threads and nuts on the extreme ends thereof, Vthe side frame elements 1 1 may be `drawn into rigid` engagement with the side edges `of the basket 3 above de-` scribed to clamp the same therebetween.

The frame elements 1.-ljthus constitute side walls for the basket 3 and may be perforated as indicated at 7'7. The upper edges of the'front wall 5 and backV walls 6 ofthe basket are vpreferably Jturned or folded over two of the tie rods 2-2 as at 40-40 disposed adjacent the said upper edges of the basket,

to position and helpsupport the basket, and y to give it a` finished rounded Aedge. Strips 8 and may be securedto theinner faces of the frame elements 1-1 under the basketbottom l andbehind thel basket` back wall 6 respec-V i "Thus by means ofthe u@ basewajai@ lbasket 3 is tightly clamped between theframe elements .1'-l, and the frame elements are suitably'spaced apart thereby; and the basket ameter and on five-eighths inch centers butV these dimensions form no essential part of my invention. To further Y strengthen the structure, the top edges of the frame elements 1 1 may be bent over at an angle to form angcs 12 12.

In their rear portions, the frame elements 1 1 are formed to provide depending fingers 13 13 thus providing substantially vertical slots 1& 111 between the 'lingers 13--13 andy the frame elements 1 1, the slots being adapted to be telescoped or straddled over the Wall of a scrubbing pail or scrubbing tanl to support the mop Wringer thereon as indicated in the drawings Where I haveshown in broken lines at 15 a scrubbingpail. The frame elements 1 1 extendV below the basket 3z and may be conneetedjtogether to stiften them and to Vaid in positioning the `Wringer in the pail by a rearwardly convexly curved band of sheet metal 16, the ends 17 of which are bent intoparallelism With the frame elements 1 1 and bolted or riveted thereto as at 18` The frame elements 1 1 are provided with aligned guidevf'ays orgrooves or slots therein.

of the basket 3V to a point adjacent its top'.

and then turning` into approximately horizontal portions 21 21 the vertical and horizontal portions being connected by a curved portion 22 of relatively large radius.

A presser foot is indicated generally at 23 formed from sheet metal and comprising a generally rectangular plannular face portion 24, generally triangular sides 25, and a stilfening` front edge portion 26, the sides 25 being disposed adjacent the frame elements 1 1 and bent at approximately right angles to the face 24 and the edge 26 being bent at an angle to the face 24. A stub shaft 27 extends through the Walls 25 ofthe footby means of suitable perforations therein'and extends outwardly from .the sides 2,5 and into the grooves 19 19 in the side frame elements 1 17 and the shaft 27 is rigidly secured'to the foot 23 by a rivet 23 passing through the shaft at approximately its middle and throughthe shaft 27 and extends into and through stifl'en andV the grooves or slots 19 in the fra-me elements 1 1.

A handle shaft 30 extends through suitable bearing perforations in the frame elements 1 1 and projects laterally from the framevelements on eaoh side.- At one end the shaft 30 has rigidly connected thereto a cam element 31 formed from a piece of relatively heavy sheet inetal and provided with an arcuate or other curved slot or groove 32, the curvaturepbeing convex rearwardly and the slot 32 being adapted to embrace one end of the shaft 29. The cam element 31 has an extension 31 thereon to which a handle 35 may be secured. l

The other end ofthe shaft` 30 has rigidly secured thereon a camV element 36 `which may be identicalwith the. cam element 31 except hat 'it is'not provided With-,the extension 341. The two cam elements '31 and 36 are rigidly secured on opposite ends of the shaft 30, the shaft extending through suitable perforations therein and nuts 37 clamping the cam elements on the shaft. lf'desired, the cam elements 31 and 36 may be keyed to .the

shaft 30. V'lha ends of the shaft 29 project through the curved camslots 32 of the cam elements 31 and 36. `Wrashers or spool heads 33 maybe disposed on the shaft 29 oneach side'of the cam elements 31 and 36 retained by nuts 38 VVith'the parts constructed as i above desc1'ibed,the handle 35 may lie-moved to rock the cram element 31 around. the axis of the shaft 30 and rock the shaft and the other cam element 36 rigidly connectedl to it. This movement of the cam elements 31 is conimunicated to the shaft 29 by the ram slots 32 andthe shaft 29 being constrained to move only' in the slots 19, is propelled therein. lilith the parts in the posit-'ion shown in Fig. 1,' the shaft is first propelled toward the left in thehorizontal portion 21 of the slot 19 and then around the curved portion 22 and then downwardly in thevertical portion 2O,`

in the latter position the parts being as shown in Fig. 4. The movement of the shaft 29 carries thefoot 23 with it and causes the shaft 27 to also travel in the slot 19.

The traveling movement of the tivosha'lts 29 and 27 mounted in the foot 23V oai-ries the foot with them and because of the shape of the slot 19 causes thefoot 23 to more from the position shown in'Fig.l 1 to the position shown in Fig. 1. By means of the curvature of the cam slots 32, the rotational movement of the cam elements 31 and 36 may be made relatively rapid and the vertical downward movement of the foot 23 relatively slow whereby a leverage is obtained by which the foot 23 may be forced downwardly with great force or application of a relatively small force to the. cam elements 31 and 36 bythe handle 35. 1 v

Also, the farther the cam elements ,are rocked the greater the leverage becomes due uit to the decreasing distance between the shaft 30 and the shaft 29. i As will beunderstood, the-maximum leverage is obtained by disposing the shaft 30 relativelynear to the vertical portion 20 of the slot 19. g

The vertical portion 2O of the kslot 19 is so disposed relative to the rear wall of the basket 3 and the shafts 29 and 27 are so disposed relatively to the face 2-1 of the foot that the foot 23 may move downwardly into the basket 5. And as will now be understood, a mop indicated generally in broken lines at 89, placed in the basket 3 by means of a handley 42 thereon, may be compressed between the face portion 24 of the foot 23 and the walls Y of the basket 3 and water therein squeezed out and drained away through the perforations in the basket and in the frame elements 1 1.

n Preferably I provide a spring 45 to return the handle 35 and the foot 23 to the positions shown in Fig. 1. of helical type coiled about the shaft 30 and anchored at one end to the shaft and at the other end anchored to an adjacent frame element 1.

As shown in F ig. 4, the face 2e* of the foot is of smaller dimension fromi'ear to front of the basket 3 than the corresponding dimension of the basket so that a space is left between the reinforcing flange QG and the front wall 5 of. the basket to accommodate the body of the mop. And the flange 26 'vexly curved, all liability of denting or injuring the wall of the pail is prevented.

By curving the cam slots 32 so that they are concave inwardly and downwardly in the operation of the wringer, the camming surface of the slot may be presented to the ends of the shaft 29 more nearly normal to the direction of movement of the shaft than would obtain, for example, with a straight slot.
